i This invention is directed to an improvement in calendars of the perpetual type, wherein the days of the month or other successive data is arranged on leaves which are successively exposed in accordance with the particular and appropriate data, the invention being more particularly to convenient means for permitting successive exposure of the leaves, with such means arranged to accommodate the bodily movement of all leaves from one position to another as is necessary in the reuse of the data contained on the'leaves.

The primary object of the present invention is the provision of a holding clip cooperating with the backing for a swingingand sliding movement, the clip being formed to engage all of the leaves in unexposed position and operable through a swinging movement, together with a particular formation of each leaf to permit a single leaf to drop to exposed position, each reverse swinging movement of the clip freeing the succeeding leaf, the sliding movement of the clip freeing all leaves or permitting the clip to be arranged'in a posltion for the return of all leaves previously exposed to an inoperative position for successive use of the data on said leaves.

The invention is illustrated in the accoun panying drawing, wherein Figure 1 is a perspective view of the calendar, the clip being shown in card-holding position.

trate its function and operation it is shown in use in connection with a perpetual calendar of a particular type. It is to be understood, however, that the particular type of perpetual calendar is of no importance in connection with the present invention so long as such calendar includes leaves bearing successive calendar data which is to be moved from an inoperative position to an'operative posiimposed sheets bound at the edges and between which on one side is arranged adisk 2 bearing the names of the days of the week, with such names capable of selective exposure through an opening 3 in the facing sheet of the backing, a similar disk 4 bearing the names of the months of the year,and with such' names selectively exposable through an opening 5 in the facing sheet of the backing, beingalso provided so that the appropriate day and month may be exposed to view by'simple manual manipulation of the respective disks, as is well understood. On the facing sheet of the backing are arranged spaced guide strips 6 on which the calendar leaves to be hereinafter described are mounted. These strips, here shown as narrow strips of sheet metal, have their lower ends underlying the facing sheet of the backing, with the terminal ends passed through openings in such facing sheet and turned down, as at 7 to hold the strips in place. The strips above the turned down ends are extended outwardly from the backing, as at 8, and upwardly parallel to the backing, as at 9, then inwardly toward the backing, as at 10, with their free ends turned up in short sectionsll which rest directly on the facing sheet of the back mg. v I i r The guide strips are more or less resilient so that the sections 11 remain in contact with the backing and yet-are capable of being manually pressed away from the backing for the insertion or removal of the leaves. As

formed, the guide strips present rectangular sections having upper-and lower portions at 109 Pics 1 right'angles to the face of the backing with which the respective leaves may cooperate.

The leaves, indicated at 12, are provided on their calendar data side with numbers corresponding to the days of the months, and near one edge each leaf is formed with slots 13 to slidably cooperate with the guide strips 6. The leaves when in inoperative position rest against the backing above the guide strips, the slots then cooperating with the inturned portion 1010f. each guide strip. .As the leaves are delivered from an inoperative to an operative position, they are moved or permitted to move over the vertical or upof the strips from which the-leaves depend, with the calendar data, which is concealed in the inoperative .position of the leaf, fully exposed to indicate the number of the. day, and the week and month shown through the proper operation ofthe disks 2 and 4, as previously described.

As the calendar is ordinarily supported 111 vertical position, it is apparent that the foremost leaf, when released from being held in an inoperativeposition, as willbe later described, will gravitate to an operative position. Therefore, in changingthe calendar from day to day, it is necessary to only release the outermost leaf of the leaves in inoperative position and permit such outermost leaf to gravitate to an operative or exposed position. When the period for which the data on the leaves expires as, for example, at the end of the month, it is necessary to return all of the exposed leaves from their operative position to an inoperative position to indicate the data of the successive months. Thus, the calendar, to be conveniently effective, must provide means for successively releasing single leaves from the inoperative position for the exposure of their data in the operative position, while at the same time providing for the bodily return of all leaves previously exposed to. an inoperative position for the reuse of their data.

The means to accomplish this result forms the subject-matter of the present invention, 5 and as indicated involves the clip'lt in the form of a narrow strip of metal having a lower main length 15, an upper relatively offset section 16, with the free end of the upper section projected outwardly at 17 and downwardly at its free end. at 18, forming a holding lip which is preferably convergent toward its free end, with such free end slightly rounded, as shown. The outwardly extending portion 17 is preferably provided with an upstanding projection 19 forming a finger hold for the manipulation of the clip.

The extreme lower or free end of the main length 15 is formed with an elongated slot 20, and the clip is arranged for cooperation with the backing by mounting the clip on standing portion 9 of the guide strips onto. the outstanding portion 8 at the lower ends.

a pivot pin or rivet 21 extending through the several sheets of the backing and through the slot 20 of the clip whereby the clip is permitted a vertical movement as well as a swinging movement. The upper offset section 16 of the clip is exposed through a slot 22 formedin the facing sheet of the backing, the upper length, by reason of the olfset, overlying the facing sheet of the backing above the slot. Furthermore, by reason of the offset upperportion, the side margins of the slot 22 form a limit for the respective swinging movements of the clip, for it is important that the swinging movements of the clip be limited in both directions at particular points in order toeffect successive release ofthe leaves. 7

. The upper edges of the leaves 12 are notched at 23, with the notches of appropriate. size to permit the free passage therethrough of the lip 18 of the clip. The notches of immediately succeeding leaves are out of alignment and arranged respectively at opposite limit positions of the clip. For example,.the notch in the first leaf to be released will bein position to align with the lip 18 of the clip when the clip has been swung to a position to engage one wall of the slot 22. The notch in the next succeeding leaf'will be arranged in the upper edge of that leaf in position to be in alignment with the lip 18 of the clip when the clip has been swung to a position to engage the opposite Wall of the slot 22. Thus, alternate leaveshave their notches in alignment with the opposite limit swinging positions of the. clip.

In normal position, all the leaves are in their inoperative positions, i. e. with their data side concealed and supported on the inturned portion 10 of the guides 6, with the clip occupying an intermediate position between the side walls of the slot 22 and thus out of line with any notches in the leaves. The distance between the upper offset portions 16 of'the clip and the lip 18 is such as to readily. accommodate the aggregate thickness of all leaves. In this connection, it is understood that, if desired and as indicated, the number 1 corresponding to the first day of the month may be printed directly on the backing instead of on a leaf, althoughthis is optional. r

When desiring to expose the data on the outermost leaf in inoperative position, the clip is swung in a direction to align with the notch inth'at particular leaf, and when the swinging movement of the clip has reached the proximate end wall of the slot 22, the lip is in alignment with the notch in the. out-- ermost leaf, the leaf is free of any retaining effect by the clip, and gravitates on the guide strips to expose its opposite side in a position to hold the guide strips. As the notch in vthesecond leaf or next succeeding leaf is at the opposite end of the limit of movement of the clip, the second leaf and thereby all successive leaves are held in inoperative position. lVhen desiring to expose the next leaf, the clip is swung to its opposite limit, aligning the lip 18 with the notch 23 in such leaf and the leaf is free forgravitation or removal to the exposed position. Thus, by merely moving the clip successively in opposite directions, the succeeding-leaves are automatically delivered from inoperative to operative or exposed position. 7 I 1 Having reached and exposed the particular leaf indicating the final dayof the particular month, it is necessary to return all leaves to inoperative position for the indication of the da vs of the succeeding month. Of course, even under the construction described, the leaves might he returned separately, moving the clip each time to permit the notch in'the leaf being returned to pass beyond the lip 18. This is a somewhat tedious operation, however, and would ordinarily not be performed by the user merely for calendar data, and thus the effectiveness of the perpetual calendar would he curtailed. Provision is made, however, for the return of all exposed leaves at a single operation, thus simply and con venientlv providing for the restoring of the calendaf for continued reuse. This is accomplished by first moving the clip upwardly through the permissible movement afforded by the slot 20. This movement is such as to dispose the extreme lower edge of the 11p 18 above the uppermost edges of the leaves when the latter are in inoperative position. All leaves may now be moved from exposed posltion to inoperative position at one t me and, having been placed in the inoperative position. the clip is simply moved downwardly to cause the lip 18 to overlie the outermost leaf. Thus, the restoration of the leaves to an inoperative position is accomplished in 2: simple. expeditious manner and one which would be ordinarily undertaken by the user of the calendar owing to the comparatively slight time and aloor involved and thus the effectiveness of the perpetual calendar is continued.

The clip, therefore, provides a means which through its swinging movement provides for the automatic release of each succeeding card selectively by merely swinging the clip in one direction oi the other, the clip also providing for the return of all exposed can-s to an inoperative position as a unit and the subsequent positioning of the clip to carry out the automatic single card discharge as described. As stated, the type of perpetual calendar is unimportantso long as it includes the successive exposure of leaves or cards bearing calendar data which is to be continually reused for calendar information.

Under these conditions, the improved clip which forms the subject-matter of the present invention is admirably adapted for the 7 each card is fully exposed, while, however,

concealing the calendar'data on that card.

The sides of the cards, therefore, whichfar'e 'not necessary for the calendar data may he used for any other purpose, such as advertising, detailed information or the like, as each card in inoperative position remains exposed as to that surface not containing calendar data as long as the previously delivered card remains in exposed'position to disclose the calendar data. Therefore, the exposed surface of the cards when in inoperative position may be used for any information, advertising or data desired.

The calendar proper may be formed in any way and the exposed surface thereof, other than that occupied by the cards, provided with other calendar data or information, as none of these details form any part of the subject-matter of the present invention and any and all variations in this particular are contemplated. I

I claim i 1. A calendar including a backing,'a plurality of calendar cards bearing calendar data, means whereby the cards may be moved from an inoperative position with the calendar data concealed to an operative position with the calendar data exposed, the similar edges of all cards being formed with notches, with the notches of alternate cards aligned and the notches ofsuccessive cardsspaced apart, a clip mounted inthe backing for swinging and sliding movement and having holding cooperation with the cards, the swinging movement of the clip freeingthe cards successively from the holding influence of the clip and the sliding movement of the clip freeing all cards from the holding influ ence of the clip.

2. A calendar including a series of cards hearing calendar data on one face, means for supportingthecards from movement to a position concealing the calendar data toa' position exposing said data, the similar edges of each card being notched, with the notches of successivec-ards spaced apart and the notches of alternate-cards inalignment, a clip mounted for swinging and sliding movement and having alip to overliethe outermost card of the cards 1n inoperative position the swinging movement oftlie cllppermittlng the lip to align with the notch ofthe outermost card to release saidcard for dellvery to an exposed position. the sliding movement of: the clip moving the lip to a position free ofits position, and prevent movementoii said cards to exposed position, the upper edges of the cards in inoperative position being formed with notches of a size to permit passage of the lip therethrough, the notches of successive cards-being arranged respectively in alignment with the opposite swinging limits of the clip, the sliding movement of the clip arranging the lip wholly'above the upper edges of the cards when in inoperative position.

4. A calendar having a backing sheet, a series'of cards, guides on which the cards are mounted, said guides being secured to the backing sheet and providing an upper or inoperative position of the cards and a lower or operative position therefor, a clip mounted on the backing for swinging and sliding movement with respect thereto, said clip extending through a slot in the backing, with the terminal walls of the slot limiting the swinging movement of the clip, the upper edges of the cards when in inoperative position being formed with notches alternately aligning with the limit swinging positions of the clip, whereby the clip at each swinging limit will successively release the foremost card, the sliding movement of the clip removing the clip from any holding influence on the cards.

5. A calendar including a backing, a plurality of calendar data bearing cards, means carried by the backing for supporting the cards for movement toward an upper inoperative position to a lower operative position, the cards when in inoperative position concealing the calendar data and when in operative position exposing the data, a clip mounted on the backing for swinging and sliding movement with respect thereto, said clip including a lip to overlie the-outermost card when the cards are in inoperative position, said cards being formed in their similar edges with notches, the notches of succeeding cards being spaced apart and the notches of alternate cards being in alignment at right angles to the backing, said clip including a lip capable of passing through the notches and adapted to overlie and hold the outermost card when the lip is out of alignment with the notch therein, means carried the backing to limit the" respective opposite swinging movements of the clip to a position to align the lip with the notches inthe cards aligned in such limit position, the sliding movement of the clip moving the lipabove the upper edges of the operatively movable to successively release the outermost card of the cards when in inoperative position to permit said card to be moved to an exposed position, said element being individually movable relative to that portion of the backing on which it is mounted to free all of the cards when in inoperative position simultaneously.
